I want to take a photo by using device camera and it will be stored in the some type of thumbnail:
function onDeviceReady() {
pictureSource = navigator.camera.PictureSourceType;
destinationType = navigator.camera.DestinationType;
}
function onPhotoDataSuccessFront(imageData) {
var smallImageFront = document.getElementById('smallImageFront');
smallImageFront.style.display = 'block';
smallImageFront.src = "data:image/jpeg;base64," + imageData;
$('#btnFrontDiv').text('Retake Front');
}
As you can see I use navigator.camera which is avaliable in cordova/phonegap.
I want to capture photo by using cordova or plain javascript.
Thanks for any advice.
Try this one

}
function getPhoto(imageData) {
var smallImage = document.getElementById('smallImage');
smallImage.style.display = 'block';
smallImage.src = imageData;
}
function capturePhoto() {
navigator.camera.getPicture(getPhoto, onFail, { quality: 50 });

thank you in advance to everybody for any help or advice.
I've been trying to piece together a combination of HTML5 video tag + the FileReader API but I haven't figured out how to get the dimensions of a video that a user is providing from their own computer.
Here is what I am referencing for width/ height:
HTML5 Video Dimensions
<video id="foo" src="foo.mp4"></video>
var vid = document.getElementById("foo");
vid.videoHeight; // returns the intrinsic height of the video
vid.videoWidth; // returns the intrinsic width of the video
But I want to know if it's possible to do this with a file from a user's computer (that they have selected via a normal input html tag).
Thanks!
A bit unclean solution using basic FileReader + Data URL.
<html>
<head>
<style>
div {
margin: 20px;
}
</style>
</head>
<body>
<h1>Get Dimensions</h1>
<div>
<label for="load-file">Load a file:</label>
<input type="file" id="load-file">
</div>
<div>
<button type="button" id="done-button">Get me dimensions</button>
</div>
<script src="//cdn.jsdelivr.net/jquery/2.1.4/jquery.js"></script>
<script>
(function ($) {
$('#done-button').on('click', function () {
var file = $('#load-file')[0].files[0];
var reader = new FileReader();
var fileType = file.type;
console.log("type", fileType);
reader.addEventListener("load", function () {
var dataUrl = reader.result;
var videoId = "videoMain";
var $videoEl = $('<video id="' + videoId + '"></video>');
$("body").append($videoEl);
$videoEl.attr('src', dataUrl);
var videoTagRef = $videoEl[0];
videoTagRef.addEventListener('loadedmetadata', function(e){
console.log(videoTagRef.videoWidth, videoTagRef.videoHeight);

reader.readAsDataURL(file);

Here is a simple and fast solution to get a video's size before upload.
It doesn't require any dependency.
const url = URL.createObjectURL(file);
const $video = document.createElement("video");
$video.src = url;
$video.addEventListener("loadedmetadata", function () {
console.log("width:", this.videoWidth);
console.log("height:", this.videoHeight);
});
const onSelectVideo = (files) => {
const file = files[0];
const url = URL.createObjectURL(file);
let videoId = "videoMain";
const video = document.createElement("video");
const body = document.getElementsByTagName("body");
video.setAttribute("src", url);
video.setAttribute("videoId", videoId);
body[0]?.append(video);
let videoTagRef = document.querySelector("[videoId='videoMain']");
videoTagRef.addEventListener("loadedmetadata", function (e) {
console.log(videoTagRef.videoWidth, videoTagRef.videoHeight);
});}
I'm trying to record audio from a website user and save the audio to my server. Many of the posts I have studied so far have referenced Matt Diamond's recorderjs. I attempted to recreate the demo at http://webaudiodemos.appspot.com/AudioRecorder/index.html by opening the source code through my browser. I copied the html, "audiodisplay.js", "recorder.js", and "main.js" and put them on my server. I also added the "recorderWorker.js" file from his GitHub site. In the recorder.js file, I changed var WORKER_PATH = 'js/recorderjs/recorderWorker.js' to var WORKER_PATH = 'recorderWorker.js';
When I run the demo I set up, I'm getting the "would you like to share your microphone.." warning and I can start the recording by pressing the mic icon on the right side. However, when I stop recording, the audio waveform doesn't show up below like in Matt's demo and the save icon doesn't become activated.
If I can get the demo up and running, the next problem I have is saving the wav file to the server instead of locally like in the demo. I've found several posts saying to use XMLHttpRequest(), however I can't really figure out how to connect those examples to recorderjs. Saving WAV File Recorded in Chrome to Server HTML5 & getUserMedia - Record Audio & Save to Web Server after Certain Time RecorderJS uploading recorded blob via AJAX
Using XMLHttpRequest to post wav or mp3 blobs to server is simple.
Just run this code wherever you have access to the blob element:
var xhr=new XMLHttpRequest();
xhr.onload=function(e) {
if(this.readyState === 4) {
console.log("Server returned: ",e.target.responseText);
}
};
var fd=new FormData();
fd.append("audio_data",blob, "filename");
xhr.open("POST","upload.php",true);
xhr.send(fd);
I prefer XMLHttpRequest to $.ajax() because it does not require jQuery.
Server-side, upload.php is as simple as:
$input = $_FILES['audio_data']['tmp_name']; //temporary name that PHP gave to the uploaded file
$output = $_FILES['audio_data']['name'].".wav"; //letting the client control the filename is a rather bad idea
//move the file from temp name to local folder using $output name
move_uploaded_file($input, $output)
Source: https://blog.addpipe.com/using-recorder-js-to-capture-wav-audio-in-your-html5-web-site/
Live demo: https://addpipe.com/simple-recorderjs-demo/
I figured out one solution, but would still welcome others related to recorderjs. I used MP3RecorderJS at https://github.com/icatcher-at/MP3RecorderJS. The demo html works if you change the top of the html from src="js/jquery.min.js" and src="js/mp3recorder.js" to wherever they're located in your server. For me, it is src="jquery.min.js" and src="mp3recorder.js" I also had to do the same thing to the "mp3recorder.js" file: var RECORDER_WORKER_PATH = 'js/recorderWorker.js'; var ENCODER_WORKER_PATH = 'js/mp3Worker.js'; changed to var RECORDER_WORKER_PATH = 'recorderWorker.js'; var ENCODER_WORKER_PATH = 'mp3Worker.js';
The program is set up to record both mp3 and wav. I wanted wav, so I made a few more adjustments to the html file. At line 55 you'll find:
recorderObject.exportMP3(function(base64_mp3_data) {
var url = 'data:audio/mp3;base64,' + base64_mp3_data;
var au = document.createElement('audio');
I changed that to:
recorderObject.exportWAV(function(base64_wav_data) {
var url = 'data:audio/wav;base64,' + base64_wav_data;
var au = document.createElement('audio');
The demo appends a new player each time you record. To prevent this, I deleted (commented out) the $recorder.append(au); part, made a new div to store the audio player, and then I clear that div each time, before the audio player is created. To upload to my server, I used a technique I learned from uploading images to a server save canvas image to server Basically, the "url" variable in line 56 was what I needed, but couldn't figure out how to put it in a universal variable to use by another function. So, I made a hidden div and made the contents of it equal to "url". I then referenced that div in a new function called "upload". I then used a php file called "uploadWav.php". I still have to figure out a way to activate and deactivate the upload button to prevent the user from uploading a blank file before recording, but that's another issue. Here's the final html and php that worked for me:

Does anyone have an idea on how to make this work?
Thanks!

I'm thinking that you are malforming your options value. Do you need to pass JSON or an actual object?
Right now you are passing an array with text in it.
options = ["{\"filePath\":\"/CapturedImagesCache/PhotoChooser-51766419-c657-46db-a53d-f09bee300a89.jpg\",\"server\":\"http://my.server.co.nz/pages/fileupload\",\"fileKey\":\"file\",\"fileName\":\"PhotoChooser-51766419-c657-46db-a53d-f09bee300a89.jpg\",\"mimeType\":\"image/jpg\",\"params\":\"value1=test&value2=param\",\"chunkedMode\":false}"]
The error seems to involve deserialization issues.
Put your getImage, uploadImage, win, fail outside of $(document).ready 's inline function call.
Reference to win and fail are actually closure, and phone gap gets it as null when it is trying to access those methods directly. Phonegap is probably expecting a global function instead of hidden function inside a function.
PhoneGap's executes its code out side javascript context, what may work in true javascript fashion may not work correctly with phonegap.
I had a problem similar to yours. I solved this, changing mimeType parameter to 'text/plain'.
Do you use params to send? If it's false I think you need send empty params.
I had this problem before, try to prepare the image in the html first, and dont take it directly from the navigator, it may not saving the taken photo in it cash ;)
In my solution I suppose to have an image tage with id ='camera_image'
img id='camera_image'...
Then i set all the variables of the image in it and I upload it (as you will see in the following code).
here's the 2 functions i used:
function takephoto(){
navigator.camera.getPicture(
function(uri){
$('#camera_image').show();
var img = document.getElementById('camera_image');
img.style.visibility = "visible";
img.style.display = "block";
img.src = uri;
uploadPhoto(img);
alert("Success");
},
function(e) {
console.log("Error getting picture: " + e);
},
{
quality: 50,
destinationType: navigator.camera.DestinationType.FILE_URI
});
// Get URI of picture to upload
var img = document.getElementById('camera_image');
var imageURI = img.src;
if (!imageURI || (img.style.display == "none")) {
alert("Take picture or select picture from library first.");
return;
}
}
for choosing an existing photo:
function choosephoto(){
navigator.camera.getPicture(
function(uri) {
$('#camera_image').show();
var img = document.getElementById('camera_image');
img.style.visibility = "visible";
img.style.display = "block";
img.src = uri;
uploadPhoto(img);
},
function(e) {
console.log("Error getting picture: " + e);
},
{
quality: 50,
destinationType: navigator.camera.DestinationType.FILE_URI,
sourceType: navigator.camera.PictureSourceType.SAVEDPHOTOALBUM
});
// Get URI of picture to upload
var img = document.getElementById('camera_image');
var imageURI = img.src;
if (!imageURI || (img.style.display == "none")) {
alert("please select a pic first");
return;
}
}
in the upload function:
function uploadPhoto(img) {
imageURI = img.src ...
ps: sorry for the formatting of my code, it doesn't fix well.
I am doing project in android phonegap.Here I want to upload images and videos to remote server.
I used the following link.
http://zacvineyard.com/blog/2011/03/upload-a-file-to-a-remote-server-with-phonegap
I also change some options like options.chunkedMode = false ,android:debuggable="true" and
. But still it shows error code 3.I am using the cordova-2.0.0.js version.Can anyone suggest some answer.
My js code is
**
<script type="text/javascript" charset="utf-8">
// Wait for PhoneGap to load
document.addEventListener("deviceready", onDeviceReady, false);
// PhoneGap is ready
function onDeviceReady() {
// Do cool things here...
}
function getImage() {
// Retrieve image file location from specified source
navigator.camera.getPicture(uploadPhoto, function(message) {
alert('get picture failed');
},
{quality: 50,
destinationType: navigator.camera.DestinationType.FILE_URI,
sourceType: navigator.camera.PictureSourceType.PHOTOLIBRARY
}
);
}
function uploadPhoto(imageURI) {
var options = new FileUploadOptions();
options.fileKey="file";
options.fileName=imageURI.substr(imageURI.lastIndexOf('/')+1);
options.mimeType="image/jpeg";
var params = new Object();
params.value1 = "test";
params.value2 = "param";
options.params = params;
options.chunkedMode = false;
var ft = new FileTransfer();
ft.upload(imageURI, "url of ther server/upload.php", win, fail, options, true);
console.log("H");
}
function win(r) {
console.log("HIIIIIiiii");
console.log("Code = " + r.responseCode);
console.log("Response = " + r.response);
console.log("Sent = " + r.bytesSent);
alert(r.response);
}
function fail(error) {
alert("There is something");
alert("An error has occurred: Code = " + error.code);
}
</script>
**
and my php code is
<?php
print_r($_FILES);
$new_image_name = "namethisimage.jpg";
move_uploaded_file($_FILES["file"]["tmp_name"], "upload/".$new_image_name);
?>
Thanks.
Have you added the URL in question to your whitelist?
e.g. in config.xml do you have something like:
<access origin="www.myurl.com" subdomains="true" />
or
<access origin="*" />
which allows all URLs.
Error code 3 is a FileTransferError.CONNECTION_ERR by the way.
